In 1976 Andre Alice Norton played in a D&D game with Gary Gygax, the co-founder of the game. She then wrote this book which was based on that game setting. It was the 1st book to be based on D&D. I thought it was very good! I liked how she brought the characters together and, no spoilers, tied it to the D&D world. I do own the sequel that she co-wrote with Jean Rabe as well. ( Pub 2006) I would recommend this to anyone who enjoys fantasy or D&D.
